Kennametal 1291035 Trao Turning Toolholder 1 in RC..23

Product Description

The KENNAMETAL 1291035 is a right-hand TRAO-style indexable turning toolholder built for precision metal cutting on the lathe. Part of the Kennametal K-Lock series, it features a 1 inch by 1 inch square shank and an overall length of 6 inches. The holder uses a clamp-style insert retention method and accepts RC..23 series inserts with a 1/4-inch inscribed circle. Neutral rake geometry at 0 degrees keeps cutting forces predictable across a range of workpiece materials. The steel construction provides the rigidity needed for stable, repeatable cuts in production and job-shop turning environments.

This toolholder is suited for external turning operations on CNC lathes and manual turning centers in both production and maintenance machining settings. The right-hand orientation positions the cutting edge for standard front-to-back turning passes. With a maximum depth of cut of 0.75 inches and a back-of-bar to cutting edge distance of 1.016 inches, it handles moderate to aggressive roughing and finishing passes. Machinists and toolroom technicians working with Kennametal RC..23 insert families will find this holder a direct fit within the K-Lock system.
